CAR-AXLE BOX.

Specification of Letters Patent N0. 32.803. dated July 9, 1861.

To all', ywhom it may concern:

lle it known that I, JAMES L. VAUGLAIN. ot' La l `a ve,tte. Tippeeanoe county. State of lndiana. have invented a new and useful Improvement in Far-Axle Boxes; and I do hereby tlet'lare the Vfollowing to be a full, rlear. and exaet description thereof. referenre being had to thy aetfompanying drawings. making part ot' this speeitiration.

My improvement relates to the -ap o1' rover of the grease or axle box of a railroad ear. Thrse rovers have to be Jfrequently removed Yl`or greasing and inspection of the axle journals a tedious operation when time is invaluable, several nnts havingl commonly to be nnserewed. and where. as sometimes orenrs these nuts become jammed or rustetl on. the parts are broken in the aet of removal and the box rendered useless. l remove these liabilities. simplify the box and greatly expedite the opening and elosing of the saine by providing in the box t'ront a pair ol tapering grooves which reeeive a wedge formed eap.

ln the aeeompanying drawings Figure l is an axial section of my box. Fig. is a similar section of the eap. Fig. 3 is a perspective external view of the box. l"1g. l

a perspective view of the journal brass.

A, are two lips o1 langes one to eat-h of the front'. vertieal edges of the. box. The grooves l inside ol these [langes narrow to- Vard their lovver ends so as to reeeive and retain the edges of a Wedge formed rap (l which is inserted trom above. The jarring of the ear.y so vl'ar from dislodging this eap. tends but to make it more seenre. heavy protuberanee or knot l) which depends from the bottom edge of the eap enables the di lodgment oth the cap by the blow ot' a han:- mer without danger of fracture.

I claim as new and of my inventions-Y- The provision of a wedge formed rap (l D and tapering grooves B to a ear axle box for the objerts specified.

In testimony ot' which invention. l herennto set` my hand.

JAMES Il. VIIILAIN.
